Thinking about upgrading to a fancy fridge freezer with an ice maker or water dispenserโbut worried about the plumbing? Youโre not alone. Many US homeowners wonder, โHow easy is it to plumb in a fridge freezer?โ The good news? With the right tools and a bit of patience, itโs often a manageable DIY projectโespecially if youโre replacing an existing unit. Letโs break it down so you can decide whether to grab your wrench or call a pro.
Do All Fridge Freezers Need Plumbing?
Short answer: No. Only models with water dispensers or automatic ice makers require a water line connection. Standard fridge freezers without these features operate just fine without plumbing.
According to the U.S. Department of Energy, about 65% of new refrigerators sold in the U.S. include built-in water dispensers or ice makersโa feature thatโs become nearly standard in mid-to-high-end models. If your new unit has either, youโll need a cold water supply line within 6 feet of the fridge location.
๐ก Pro Tip: Check your modelโs specs before buying. Brands like Samsung, LG, and Whirlpool clearly label โplumbedโ vs. โnon-plumbedโ versions.
What Tools and Materials Do You Need?
Before you start, gather these essentials:
- ยผ-inch flexible copper or braided stainless steel supply line (avoid plasticโitโs prone to leaks)
- Saddle valve or push-fit shut-off valve (modern codes often ban saddle valves; use a T-valve with compression fitting instead)
- Adjustable wrench
- Drill and hole saw (if running line through cabinets)
- Teflon tape
- Bucket and towels (for potential spills)
Most hardware stores sell fridge installation kits (~$20โ$35) that include everything except the shut-off valve.

Step-by-Step Guide: How to Plumb In Your Fridge Freezer
Follow these steps carefullyโsafety first!
Step 1: Turn Off the Main Water Supply
Locate your homeโs main water shutoff (usually in the basement or utility room). Turn it off to prevent flooding during installation.
Step 2: Install a Dedicated Shut-Off Valve
Never tap directly into a pipe without a valve. Use a ยผ-inch T-fitting on your nearest cold water line (often under the kitchen sink). Install a quarter-turn ball valveโitโs code-compliant and reliable.
โ ๏ธ Note: Many local plumbing codes (like UPC in California) prohibit self-piercing saddle valves due to leak risks. See plumbing standards on Wikipedia.
Step 3: Run the Supply Line to the Fridge
Drill a ยฝ-inch hole through the cabinet wall or floor (if needed). Feed the supply line from the valve to the back of the fridge. Keep the line as short and straight as possibleโcoils can restrict flow.
Step 4: Connect to the Fridge
Attach the line to the fridgeโs water inlet (usually at the bottom rear). Hand-tighten, then give ยผ turn with a wrenchโdo not overtighten, or youโll crack the fitting.
Step 5: Test for Leaks
Turn the water back on. Open the fridgeโs water dispenser (or wait 10 minutes for ice maker cycle). Check all connections with a dry paper towel. Even a slow drip can cause major damage over time.
Step 6: Flush the System
Run 2โ3 gallons of water through the dispenser to clear air and debris from the line. This prevents cloudy ice or odd tastes.
Plumb In vs. Non-Plumbed: Pros and Cons
| Feature | Plumbed Fridge Freezer | Non-Plumbed Model |
|---|---|---|
| Convenience | โ Instant ice & cold water | โ Manual ice tray filling |
| Installation Cost | $100โ$300 (DIY: ~$30) | $0 |
| Flexibility | โ Must stay near water line | โ Can place anywhere |
| Maintenance | โ Filter changes, leak risk | โ Minimal upkeep |
| Home Value | โ Adds modern appeal | Neutral |
If you rent or plan to move soon, a non-plumbed model might be smarter. But for long-term homeowners, plumbing in adds daily convenience.
Common Mistakes to Avoid
- Using plastic tubing โ It cracks over time. Stick with copper or braided steel.
- Skipping the shut-off valve โ Makes future repairs messy and risky.
- Ignoring the water filter โ Most plumbed fridges require a filter (replace every 6 months).
- Running line near heat sources โ Keep away from ovens or dishwashers to avoid pressure issues.
A 2023 HomeAdvisor report found that 38% of DIY fridge plumbing failures were due to improper valve installationโso donโt rush this step.
When to Call a Professional
Consider hiring a licensed plumber if:
- Youโve never worked with water lines before
- Your kitchen lacks a nearby cold water source
- Local codes require permits for new plumbing taps
- Youโre installing during a full kitchen remodel (better to integrate early)
Average cost: $150โ$250, but it includes peace of mind and warranty coverage.
FAQ Section
Q1: How long does it take to plumb in a fridge freezer?
A: For a confident DIYer, 1โ2 hours. First-timers may take 3โ4 hours. Allow extra time if drilling through walls or installing a new shut-off valve.
Q2: Can I use my existing water line from an old fridge?
A: Yesโif itโs in good condition (no kinks, corrosion, or plastic tubing). Replace the line if itโs over 5 years old or shows wear.
Q3: Do I need an electrician too?
A: No. Fridges plug into standard 120V outlets. Just ensure the outlet is grounded and not shared with high-wattage appliances.
Q4: Why is my ice maker not working after plumbing?

Q5: Is plumbing a fridge freezer up to code?
A: Yesโas long as you use approved materials (e.g., NSF-certified tubing) and a proper shut-off valve. Always check local building codes first.
Q6: Can I disconnect and move a plumbed fridge later?
A: Absolutely. Turn off the valve, disconnect the line, and cap both ends. Store the fridge upright for 24 hours before re-plumbing.
